In this matter the applicant pleaded guilty to a charge of knowingly taking part in the cultivation of a large commercial quantity (250) of cannabis plants grown by enhanced indoor means. The standard non parole period of 10 years was applicable. The applicant was found to have a limited role in the operation, consisting mainly of knocking down a wall, diverting some electrical leads and removing carpeting. The applicant had a prior conviction of supplying more than a small but less than an indictable amount of heroin. He was towards the lower end of functioning intelligence. Special circumstances were found and one offence was taken into account on a Form 1. He appealed against the sentence of a non parole period of 3 years with a balance of term of 2 years on the grounds that it was manifestly excessive. The appeal was unsuccessful.
19 In evaluating the sentence, the Court may have regard to statistics such as those provided by the Judicial Commission of New South Wales and to similar cases in determining sentence patterns and the appropriate sentencing range: R v Bloomfield (1998) 44 NSWLR 734 at 739. Caution must be exercised in the use of such material as the sentence depends upon the facts of each case and bare statistics tell the judge very little which is useful and see Wong v R [2001] HCA 64; (2001) 207 CLR 584.
20 The cases to which reference was made by senior counsel for the applicant are insufficient in number to establish a reliable sentencing range. However, the decisions in this Court in Bui, Nguyen and Phan establish that a sentence in the order of three years non parole period and a balance of term of two years prima facie would not be regarded as manifestly excessive in the case of an offender whose role was toward the lower end of the scale and where the number of plants was in the range of 200-300.
21 His Honour concluded that the applicant's criminality fell just below the mid range. This finding appears somewhat favourable to the applicant when regard is had to the very high level of criminality resulting from his total involvement in all aspects of the enterprise even though the number of plants was at the lower end for this offence. However, the finding was not challenged by the Crown.
22 This court has held that the standard non parole period remains a reference point, benchmark or guidepost, when there has been a plea of guilty: R v AJP [2004] NSWCCA 434; (2004) 150 A Crim R 575 per Simpson J at [37]. In R v Knight; R v Biuvanua [2007] NSWCCA 283; (2007) 176 A Crim R 338 Howie J stated, at [47]:
"Even after a plea of guilty there must be an appropriate relationship between the standard non-parole period and the objective criminality of the offence regardless of the other matters that may be taken into account by way of mitigation."
23 As has been observed on a number of occasions, the implementation of a relatively high standard non-parole period will lead inevitably to an increase in sentencing for the relevant offence: AJP, R v AD [2005] NSWCCA 208 per Howie J at [43] and De Rosiers v Regina [2006] NSWCCA 16; (2006) 159 A Crim R 549 per Latham J at [36].
24 When allowance is made for the higher degree of criminality involved in the case of the applicant, it is apparent the sentence imposed is consistent with the sentences upheld in the Court of Criminal Appeal in Bui, Nguyen and Phan.
25 Sentencing involves a discretionary judgment. There is no single correct sentence and judges at first instance are to be allowed as much flexibility in sentencing as is consonant with consistency of approach and as accords with the statutory regime that applies: Markarian v R [2005] HCA 25; (2005) 228 CLR 357.
26 In sentencing the applicant, his Honour had regard to the nature of the offence and other objective factors, the maximum penalty, the reference point provided by the standard non-parole period and the applicant's subjective case. The sentence is high but, in my opinion, was open in the proper exercise of his Honour's sentencing discretion.
